Abstract

La présente invention concerne un procédé permettant de préparer un matériau polyuréthanne dont la température de transition vitreuse n'est pas inférieure à 25 ·C. Ledit procédé consiste à faire réagir un polyisocyanate avec une composition réagissant avec l'isocyanate, optionnellement en présence d'eau en une quantité inférieure à 5 % en poids de la composition ci-dessous réagissant avec l'isocyanate, la réaction s'opérant à un indice d'isocyanate de 80 à 140. Le polyisocyanate comprend a) 80-100 % en poids de diisocyanate de diphénylméthane comprenant au moins 40 %, de préférence au moins 60 % et idéalement au moins 85 % en poids de diisocyanate-4,4' de diphénylméthane et/ou une variante dudit diisocyanate de diphénylméthane, laquelle variante est liquide à 25 ·C et présente une valeur NCO d'au moins 20 % en poids (polyisocyanate a), et b) 20-0 % en poids d'un autre polyisocyanate (polyisocyanate b). La composition réagissant avec l'isocyanate comprend a) 80-100 % en poids d'un polyol de polyéther présentant une fonctionnalité nominale moyenne de 3-8, un poids équivalent moyen de 200-2000, un poids moléculaire moyen de 600-8000, une teneur en oxyéthylène (EO) de 50-100 % et de préférence de 75-100 % en poids et une teneur en hydroxyles primaires de 70-100 % calculée à partir du nombre de groupes hydroxyles primaires et secondaires dans le polyol, b) un allongeur de chaîne et/ou un agent de réticulation réagissant avec l'isocyanate en une quantité telle que le rapport de bloc dur est égal à 0,60 ou plus, et de préférence à au moins 0,65, et c) 20-0 % en poids d'un ou de plusieurs autres composés réagissant avec l'isocyanate, à l'exception de l'eau, la quantité de polyol a) et de composé réagissant avec l'isocyanate c) étant calculée à partir du montant total dudit polyol a) et dudit composé c).
